I have made it’s fix. You can download it at http://www.ishbir.com/wpfix1.zip. Unzip the file to you wp-admin directory and replace the previous options.php file. Test it. If any problem mail me a at webmaster(at)ishbir(dot)com.

Please see the differences in the line $goback = add_query_arg('options-general.php?updated', 'true', $_SERVER['HTTP_REFERER']);. Firstly it was $goback = add_query_arg('updated', 'true', $_SERVER['HTTP_REFERER']);

Please check it again or download it again and check. This line of ‘$goback’ is different. Open both the files and then navigate to the same line and check it carefully becuase sometime even I can’t see the differences.
